SiNNEn, a subwhich are a part of this specification.

This invention relates to improvements in cash registers adapted to indicate and register the amount of each purchase and more particularly yto the key board and connected mechanism.

It4 is one of the objectsof this invention to provide a cash register in which the keyboard and connected mechanism is of simple construction, strong and durable and not liable to get out of order. i

A- further object of the invention is to provide a cash register in which the keys are locked in adjusted position to display lthe amount of purchase until released by provided with a curved 4in the rear thereof; Fig.

operating a key.

With thepabove, and other objects in view,/

the invention consists of the improved cash register and its parts and combinations as set forth in the claims, and all equivalents thereof. v, f

In the accompanying drawings in which tlrl same reference characters .indicate the views: Figure 1 is a vertical transverse sectional view of the' cash register taken on line 12 of Fig. 3, a part broken away to show another part 2 is a similar view' thereof with the parts 1n indicating positions; Fig. 3 is a horizontal sectional view of one end portion of the cash register taken on line S-Sof Fig. 1; Fig. 4 is a vertical longitudinal sectional View on line l.1 -L1; of Fig. 1 and, Fig. 5 is a -detail view of a portion of one of the indicating strips.

Referring to the drawings the numeral 8y indica-tes the rectangular vcasing which is front portion 9 and with indicator openings 10. Partitions 11 dividingy the casing longitudinally -into a plurality of key compartments 12 have eX- tended therethrough a `fixed horizontal shaft 13. j -The axial line of the shaft corresponds to the axis of thecurve of journaled y, on said being had to the and extend thereof taken A the front portiony ingly a slight of the casing and segmental members 14 shaft project l forwardly therefrom `to points adjacent to the curved front and have their forward edges 15 correspondingly curved.I rlfhe rearwardly eX- tending edges. of these members are semicircular in shape' and are provided with teeth forming half gears 16 which mesh with registering pinion's 17. Finions 17 are independently mounted on sleeves 1S and 19 and on .a small shaft 20 andthe sleeve l 1S is partly telescoped over the sleeve 19 and the sleeve 19 in turn is partly telescoped over the shaft S20 to provide for conveying the partial rotations of the different pinions to the registering mechanism (not shown) in the ordinary manner. Coiled springs 21 connected to the half geared portions of the members and to the partitions 11 serve to forward vportions of the said'membersin their uppermost positions and against the stop pins 22 which project from the partitions.

Each segmental-member carries nine keys indicated by the numeral 23 which are numbered in consecutive order, beginning at the top, from one to nine inclusive. These keys are pivoted tothe sides of and near the outer peripheries of the members by vscrews 241 radially outwardly from said. members and-'through elongated slots E25 provided in the curved front portion of the casing.

Stop pins 2G and 27 projecting from'the sides of the segmental members and posi-A tioned respectively above and below the inner ends of each key are adapted to permit a limited downwar'd movement of each key before the particular segmental member is moved to which the keys are connected.

Coiled springs 28 connected to the forward portion portion of each key immediately thereabovev tends to hold the. Vinner ends of said keys l Rossato of each key and to the inner against the stopv pins 27. The keys vare ybe swung inwardly to a position to engage ythe free ends of stop levers 30 which are pivoted to the casing partitions. These stop levers are positioned below the lower-most keys when said keys are in their uppermost positions and their freeends are held yield- .dist-ance above stop' brackets- 531 also,- fastened to the partitions.` Coiled springs 32 connected to the hubs of the stop levers and to the hubs of pawls normally hold the stop levers spaced from the stop brackets. The pawls 33 are also pivoted to the partitions andare provided with later-- ally extending pins 34 which engage shoulders 35 formed on the stop levers and serve to prevent said stop levers from swinging upwardly andthe pawls from swinging forwardly. These pawls 33 vwhen released from the shoulders are adapted to swing forwardly and engage the teeth of segmental ratchet bars 36 fastenedto the sides of the segmental members and prevent the segmental members from swinging farther downward. The segmental members are also provided with projecting pins 37 which extend from the lower portions of the said members and are positioned to swing the pawls 33 rearwardly out of engagement wit-h the segmental bars and into engagement with the shoulders of the pawls and lock said pawls in said positions when the segmental members are swung upwardly.

1n order to provide for holding the segmental members temporarily in the positions to which they have been moved a shaft 38 extending longitudinally above the segmental arms has mounted loosely thereon depending arms 39 which extend alongside of the segmental members and their lower ends 40 are curved forwardly and formed in the shape of teeth which normally engage the teeth of segmental ratchet bars 4l fastened to the segmental members and interposed between the said members and the rack bars 3G. Springs 42 connected to the upper ends of these arms and to the casing hold the said arms yieldingly in engagement with the ratchet bars and short arms 43 rigidly connected to the shaft 38 are provided with horizontal projections 44 which extend in front of the depending. arms and swing the arms out of engagement with the ratchet bars when the shaft is turned. A shaft arm 45 rigidly mounted on `the shaft has a releasing, key 4G connected to the lower end of said arm which extends through an opening 47 in the casing is provided with a head 48. A coiled spring 49 interposed between the head and the casing holds the short arms 43 against the stops 50 to permit the dependingr arms to independently engage their respective ratchets and the'releasing key serves' to disengage said depending arms from the ratchet bars when the said' key is pressed inwardly.

The tw'o ratchet bars carried by each segmental member have their respective teeth inclined in opposite directions to properly cooperate with the pawls and the depending.

arms.

lVhen the segmental members have been moved to indicating positions and it is desired to release the said members, the releasing key is pressed inwardly to accomplish this result as before stated and in or-l of releasing pins 53 which are carried by the segmental members and which engage and lift the latches when the said members swing to their uppermost positions.

To provide a visible indication of the amount registered each segmental member Ahas connected to the upper portion thereof the end of a tape 54 which extends from said member upwardly and over idle rollers and 56 and then downwardly and is con, nected to the upper end of a coiled spring 57 the lower end of which is connected to the bottomportion of the casing. rlhese tapes each have the numerals from one to nine inclusive printed thereon and arranged in consecutive order and positioned to show the proper numbers through the indicator openings l0 that have been registered on the keys.

In the form of the register shown in the drawings but three lines or banks of keys are indicated but it is to be understood that the invention contemplates a register provided with any number of keys.

In operation when one of the keys is depressed it will first swing downwardly on its pivot until its rear end engages one of the stop pins. In this position 'the downwardly extending finger will have swung rearwardly anda further pressure on the key will force the segmental member downwardly until the finger strikes the stop lever and it in turn strikes the stop bracket. This movement will pull o-n the tape vand indicate the number of the key depressed and the segmental membcr will turn one of the regis-- tering pinions toregister the amount. The stop lever in swinging on its pivot will move its pawl into engagement with the ratchet lbar of the respective member and prevent further downward movement of said member. At

the same time the lower end of the depending arm will engage the other ratchet bar on said member and lock the member in depressed position. Other keys may now be depressed in the same manner and when the desired amount is indicated, the releasing key is pressed inwardly to release all of the registering keys and they will swing back to their original positions. ln swinging back the depending arms will be released fromtheir respective latches and again engage"'the rack bars.

From the foregoing description lit Will be seen that theregister is very simple in construction and operation and is Well adapted for the purpose desired. v
